(ORDO NEWS) — Researchers at Canadian universities have grown a millimeter-long cardiac ventricle in the lab. Its main feature is that it beats like a real heart and even pumps fluid.
Part of the heart was grown from cells taken from the cardiovascular tissues of young rats. The scientists then printed a scaffold layer from the polymer, on which the tissue was grown.
So it was possible to imitate the location of the fibers of the heart muscle of the human left ventricle. The model is made of several layers of cells like a real heart.
The artificial heart beats thanks to a series of small electrical discharges. This model allows the study of new methods of treatment of cardiovascular diseases.
